40 CARABID^. CARABUS. 



the antennae, four joints at the base of the latter black and 

 glabrous, the remainder fuscous and pubescent. Thorax quadrate, 

 slightly dilated between the anterior angles and the middle, 

 broadly margined behind, with the posterior angles deflexed and 

 produced, disk rugosely punctate, black with the lateral margins 

 broadly violaceous. Elytra black, convex, elongate, narrow at 

 the shoulders, dilated in the middle, finely granulated, some- 

 times the granules are united here and there so as to form slightly 

 elevated lines but irregularly disposed, margins broad, sub- 

 punctate, bright coppery or golden violet or brilliant purple ; 

 body beneath and legs black. Length 12 lines. 



Common in gardens, in gravel-pits and on heaths and path- 

 ways, &c. in the spring ; very abundant in the south and midland 

 counties of England ; in Scotland and in Ireland. 



C. purpurascens, Fab., is a variety of this insect ; and C. exas- 

 peratusy Dufts., has no indigenous examples to confirm it ; the 

 individuals published under that name and captured in the Isle 

 of Portland are likewise varieties of this species. 



11. C. convexus : niger, limbo cyaneo.; elytris convexis, subtiliter 



crenato-striatis triseriatim punctatis.

Shorter and narrower than glabratus, black with the margins 

 of the thorax and elytra cyaneous. Head slightly punctured 

 and with an impression on each side between the antennae. Thorax 

 nearly quadrate, very slightly narrowest behind, the basal margin 

 deeply notched, the posterior angles rounded, disk with a slight 

 dorsal line and very much punctured and rugose. Elytra short, 

 ovate, convex, closely striated, the striae obsoletely punctured, 

 with narrow elevated granulated interstices and three series of 

 larger impressions ; underside black and shining. Length 8 lines. 



A doubtful native; there are two examples in the British 

 Museum; one in the collection of Mr. MacLeay and another in 

 that of Mr. Vigors, but the locality of none of them is known. 

 The Rev. A. Matthews informs me that he has an example which 

 was taken in Winstanley Park in Sept. 1835. 



12. C. glabratus: oblong o-ov a tus, niger ; thorace tenuiter reti- 



culato-rugoso ; elytris convexis, subtilissime granulatis.
